Summer in Western North Carolina can bring unexpected afternoon thunderstorms that may create dangerous driving conditions in minutes. When rain hits our mountain roads, the risk of hydroplaning increases significantly, putting drivers, passengers, and vehicles in danger. Understanding how to prevent hydroplaning accidents and knowing what to do if your vehicle is damaged in a summer storm collision can help keep you safe during the unpredictable summer weather months.
Understanding Hydroplaning: When Your Tires Lose Contact
Hydroplaning occurs when a layer of water builds between your tires and the road surface, causing your vehicle to lose traction and control. This dangerous situation happens when your tires cannot channel water away quickly enough, effectively creating a thin water barrier that prevents direct contact with the road.
The physics behind hydroplaning is straightforward but often misunderstood. When driving on wet roads, your tires are designed to disperse water through their tread patterns. However, at certain speeds or when water is too deep, your tires cannot push away enough water, and they begin to ride on top of the water rather than the road.
Several factors determine whether your vehicle will hydroplane:
- Speed: The faster you drive on wet roads, the greater the risk
- Water depth: Even shallow puddles can cause hydroplaning at high speeds
- Tire condition: Worn tires with reduced tread depth cannot channel water effectively
- Vehicle weight: Lighter vehicles may hydroplane more easily than heavier ones
- Road surface: Smooth, worn pavement holds more water than textured surfaces
Contrary to popular belief, hydroplaning can occur at speeds as low as 35 mph with just 1/12 inch of water on the road—that's less than the height of a new penny.
High-Risk Conditions for Hydroplaning in Western North Carolina
Our region's unique geography and weather patterns create specific hydroplaning risk factors that local drivers should understand:
Weather Patterns That Increase Risk
Western North Carolina experiences intense summer thunderstorms that can dump significant rainfall in short periods. These storms are often localized, meaning you might drive from dry conditions into a heavy downpour with little warning. The first 10-15 minutes of rainfall are particularly dangerous as water mixes with road oils to create an especially slippery surface.
Local Road Conditions
The mountainous terrain in our region creates numerous hydroplaning risk factors:
- Drainage challenges: Mountain roads often have limited drainage capabilities
- Winding roads: Curves reduce tire traction, compounding hydroplaning risks
- Elevation changes: Water naturally flows downhill, creating deeper puddles in low-lying areas
- Summer construction: Road work common during summer months can alter normal drainage
Our blog post about driving on mountain roads contains a detailed discussion of this topic.
High-Risk Areas
Some locations in our service area (Asheville, Hendersonville, and Brevard) are particularly prone to standing water during storms:
- Intersections with poor drainage
- Low-lying sections of I-26, especially near the Asheville Airport
- Mountain valley roads that collect runoff
- Areas with recent construction that may have altered natural drainage patterns
Vehicle Factors That Increase Your Hydroplaning Risk
Your vehicle's condition plays a crucial role in preventing hydroplaning accidents. Here are the most important factors to consider:
Tire Tread Depth and Condition
Tire tread is your first line of defense against hydroplaning. The grooves in your tires are specifically designed to channel water away from the contact patch—the part of your tire that touches the road.
The legal minimum tread depth is 2/32 of an inch, but for wet conditions, safety experts recommend at least 4/32 of an inch. You can check your tread depth with a simple quarter test:
- Insert a quarter into the tread groove with Washington's head upside down
- If part of Washington's head is covered by the tread, you have at least 4/32" of tread remaining
- Check multiple locations across each tire, as wear can be uneven
Uneven tire wear also increases hydroplaning risk. If your tires show signs of cupping, feathering, or one-sided wear, your vehicle may need an alignment or other maintenance.
Vehicle Weight Distribution
How weight is distributed in your vehicle affects hydroplaning risk. When carrying heavy loads:
- Ensure proper weight distribution according to your vehicle manufacturer's recommendations
- Avoid overloading, which can affect handling and braking distance
- Be especially cautious when towing trailers in wet conditions, as the additional weight behind your vehicle can push it forward during hydroplaning
Speed and Driving Behavior
Your driving behavior is perhaps the most controllable factor in preventing hydroplaning:
- Reduce speed by at least 5-10 mph below the speed limit during rain
- Increase following distance to at least 5-6 seconds in wet conditions
- Avoid sudden movements (braking, accelerating, or turning)
- Drive in the tracks of vehicles ahead when possible, as they've already displaced some water
Prevention Strategies: Staying Safe During Summer Storms
Preventing hydroplaning requires both proper vehicle maintenance and appropriate driving techniques:
Proper Tire Maintenance
Your tires are your vehicle's only contact with the road, making their maintenance critical for wet-weather safety:
- Regular rotation: Rotate tires every 5,000-7,000 miles to ensure even wear
- Proper inflation: Check tire pressure monthly and before long trips
- Timely replacement: Replace tires when tread depth approaches 4/32" for wet climates
- Appropriate tire selection: Consider tires with wet-weather performance ratings for our region
Defensive Driving Techniques for Wet Weather
- Scan the road ahead for standing water and potential hazards
- Avoid cruise control in wet conditions, as it can delay your reaction time
- Drive in the highest gear possible (for manual transmissions) to reduce torque to the drive wheels
- Follow the tracks of vehicles ahead when safe to do so
- Reduce speed before entering curves or areas where water might collect

Vehicle Preparation for Storm Season
Before summer storm season arrives:
- Have your tires inspected for proper tread depth and condition
- Check that your windshield wipers are in good condition and replace them if needed
- Ensure all lights are functioning properly for visibility
- Verify that your brakes are in good working order
- Consider a preventative maintenance check to identify potential issues
What To Do If You Start Hydroplaning
Despite best prevention efforts, hydroplaning can still occur. If you feel your vehicle begin to hydroplane, follow these steps:
Step-by-Step Emergency Response
- Stay calm and fight the natural instinct to make sudden movements
- Ease off the accelerator gradually—don't slam on the brakes
- Hold the steering wheel firmly with both hands at the 9 and 3 o'clock positions
- Steer gently in the direction you want the front of the vehicle to go
- Wait for your tires to regain traction before accelerating or braking
Recovery Techniques
Once your vehicle begins to regain traction:
- Continue to drive at a reduced speed
- Turn on your hazard lights if appropriate to alert other drivers
- Consider pulling over when safe to collect yourself and check your vehicle
- Proceed with extra caution, as conditions that caused the initial hydroplaning likely still exist
Common Mistakes to Avoid
- Don't panic brake: Slamming on brakes during hydroplaning can worsen the skid
- Avoid jerking the steering wheel: Sudden movements destabilize the vehicle further
- Don't accelerate: Adding power increases the likelihood of spinning out
- Don't ignore warning signs: If you feel the steering become "light" or hear tire noise decrease, you're likely beginning to hydroplane
After a Hydroplaning Accident: Next Steps
If hydroplaning leads to a collision, follow these important steps:
Immediate Safety Steps
- Check yourself and passengers for injuries
- Move to a safe location if possible
- Turn on hazard lights and set up reflective triangles if available
- Call 911 if there are injuries or significant damage
- Exchange information with other involved parties
Damage Assessment
After ensuring everyone's safety, assess your vehicle for damage:
- Check for obvious damage to the exterior
- Look for fluid leaks under the vehicle
- Note any changes in handling, steering, or braking
- Document damage with photographs from multiple angles
Remember that damage from hydroplaning accidents often extends beyond what's visible. Even low-speed impacts can cause alignment issues, suspension damage, or frame bending.
Insurance Considerations
When dealing with your insurance company:
- Report the accident promptly
- Provide detailed information about weather and road conditions
- Follow their guidance for claims processing
- Consider requesting a professional damage assessment, even for seemingly minor damage

Frequently Asked Questions About Hydroplaning and Repairs
How can I tell if my tires are safe for wet weather driving?
Check your tire tread depth using the quarter test mentioned earlier. Also, inspect tires for uneven wear, bulges, or damage. When in doubt, have your tires professionally inspected, especially before the summer storm season.
Does vehicle type affect hydroplaning risk?
Yes. Lighter vehicles tend to hydroplane more easily than heavier ones. Vehicles with wider tires may also be more susceptible because they need to displace more water. Additionally, front-wheel-drive vehicles sometimes handle hydroplaning recovery differently than rear-wheel-drive vehicles.
What's the most common mistake drivers make during rainstorms?
The most common mistake is failing to reduce speed appropriately for conditions. Remember that posted speed limits are designed for ideal conditions. During rainfall, especially in the first 10-15 minutes when oil residue makes roads particularly slippery, you should reduce speed by at least 25%.
How soon after a hydroplaning accident should I get my vehicle inspected?
You should have your vehicle professionally inspected as soon as possible after any accident, even if damage seems minor. Hidden damage can worsen over time and potentially lead to unsafe driving conditions or more extensive repairs later.
Will my insurance cover hydroplaning accident damage?
Most comprehensive and collision insurance policies cover damage from hydroplaning accidents, but coverage details vary. Contact your insurance provider promptly after an accident and follow their specific claims process.
